Episode Overview

ASCP Esty Talk Ep. 350 – The Rogue Pharmacist: Free Radicals features host Maggie Stasik and guest Benjamin Knight Fuchs, pharmacist and skincare formulator. The episode breaks down the misunderstood world of free radicals, their dual roles in skin health, and why antioxidants are crucial—especially for estheticians. Using accessible analogies and science-backed explanations, Ben demystifies oxidation and explains how estheticians can apply this knowledge in their practice.

Main Theme

The episode centers on free radicals: what they are, why they’re not always “the enemy,” how they cause damage in the skin, and the critical role of antioxidants in both internal and topical skincare—particularly following treatments like peels, lasers, and microdermabrasion.

Key Discussion Points & Insights

1. Understanding Free Radicals (00:20–05:40)

• What Are Free Radicals?

  • Ben uses the analogy of a “Mickey Mouse atom,” with each ear representing an electron. A healthy atom has two “ears.” When something steals an “ear,” you’re left with a destabilized, reactive atom—a free radical.
    • “Think of an atom as Mickey Mouse … These Mickey Mouse atoms like to have two ears … This unhealthy Mickey Mouse ear with one space is what we call free radical.” – Ben Fuchs [01:10]

• How Are Free Radicals Formed?

  • Oxygen is the main culprit, responsible for the process called “oxidation.”
  • Other environmental factors like chlorine, fluoride, and sunlight also contribute.
    • “The most important substance in our environment that knocks off the ear is oxygen. And this is what makes oxygen such a tricky substance to work with…” – Ben Fuchs [02:40]

• Oxidation Visible in Everyday Life:

  • Color changes due to bleach or fire are examples of large-scale oxidation/free radical activity.
    • “Fire is the visible observation of the stealing of Mickey Mouse ears … when it happens in a tiny little amount, you can’t really see it… But in a fire, you’re seeing billions, trillions maybe, of Mickey Mouse ears being stolen, and that’s observable as fire.” – Ben Fuchs [05:00]

2. Free Radical Damage in Skin & Health (05:41–08:30)

• Cell Membrane Vulnerability:

  • Free radicals hunt for electrons, often attacking cell membranes, proteins, and DNA.
    • “Cell membranes are very susceptible to damage from these rogue atoms … when cells are damaged, when the membranes are damaged, they start to release inflammatory fats.” – Ben Fuchs [06:50]

• Health Consequences:

  • Ongoing damage leads to inflammation, accelerated aging, mutations, and possibly cancer.
    • “When you have enough of these rogue atoms … eventually the DNA, the genetics, is going to get damaged. This is where mutations and ultimately cancers can come from.” – Ben Fuchs [07:30]

3. The Antioxidant Solution & Its Challenges (08:31–12:35)

• How Antioxidants Work:

  • Antioxidants are molecules with extra, loosely-held electrons (the “loose Mickey Mouse ear”), ready to donate to free radicals and neutralize them.
    • “That’s an antioxidant. Exactly. And antioxidants are so important … because they can contribute an ear to the atom so it can be filled so it doesn’t have to steal.” – Ben Fuchs [09:09]

• The Chain Reaction Problem:

  • Once an antioxidant donates an electron, it becomes a pro-oxidant and can, in turn, do damage unless replaced by another antioxidant.
    • “Once they do their work, they now become pro oxidants because they have a hole. And now they’re gonna go steal from a cell membrane…” – Ben Fuchs [09:29]
  • Continuous supply is needed—like musical chairs, the chain must never stop.

• Diet & Supplementation:

  • Best defense is a steady intake of antioxidants from diet (produce, especially—since plants are exposed to oxidative stress and thus rich in antioxidants) and supplements.
    • “You have to have a steady stream of antioxidants coming into the system. And that’s why it’s important to supplement and that’s why it’s important to make sure you’re eating your vegetables.” – Ben Fuchs [10:35]

4. Special Focus: Vitamin C, E, and Fats (12:36–13:50)

• Vitamin C:

  • Powerful antioxidant (fantastic at donating electrons), but its effectiveness makes it unstable and quick to turn into a pro-oxidant—the reason vitamin C serums often turn brown.
    • “Vitamin C is such a wonderful antioxidant, it’s also a pro oxidant. Anytime something is a really good antioxidant, it’s also going to lend itself to pro oxidation because it’s giving up its Mickey Mouse ear…” – Ben Fuchs [11:48]

• Vitamin E & Fats:

  • Fats are extremely susceptible to oxidation, with oxidized fats (lipid peroxides) being especially toxic.
    • Vitamin E, selenium, and alpha-lipoic acid are vital for protecting fats—and by extension, anti-aging and overall health.
      • “Protecting fats is absolutely critical. Probably the most important thing you could do for anti aging is protect your fats from oxidation…” – Ben Fuchs [12:28]

• Practical Takeaway:

  • Avoid heating oils, as heat accelerates oxidation—consume fresh oils and use more stable options like coconut oil or butter.

Notable Quotes & Memorable Moments

• Mickey Mouse Analogy

  • “Think of an atom as Mickey Mouse … These Mickey Mouse atoms like to have two ears … This unhealthy Mickey Mouse ear with one space is what we call free radical.” – Ben Fuchs [01:10]

• On Fire as Oxidation

  • “Fire is the visible observation of the stealing of Mickey Mouse ears … you’re seeing billions, trillions maybe, of Mickey Mouse ears being stolen, and that’s observable as fire.” – Ben Fuchs [05:00]

• On Antioxidant Supplementation

  • “You have to have a steady stream of antioxidants coming into the system. … That’s why it’s important to supplement and that’s why it’s important to make sure you’re eating your vegetables.” – Ben Fuchs [10:35]

• On Vitamin C’s Downside

  • “Anytime something is a really good antioxidant, it’s also going to lend itself to pro oxidation because it’s giving up its Mickey Mouse ear so effectively.” – Ben Fuchs [11:48]

• On Lipid Peroxides’ Danger

  • “Lipid peroxides are the most dangerous of the oxidized materials in the body. … Protecting fats is absolutely critical. … That’s why things like vitamin E and selenium and alpha lipoic acid are so, so important for anti aging…” – Ben Fuchs [12:28]
